When one moves the mouse pointer over the hovercard and then back over the link (without leaving the combined area of link and hovercard), the hovercard disappears and reappears.
Expected behaviour would probably be that the hovercard is shown cuntinouously in this scenario.
Detailed steps to reproduce:
- Move the mouse over a link and watti for the hovercard to appear (best visible when the tip of the hovercard is located over the linked area)
- Move the mouse cursor over to the hovercard (it should stay visible)
- Move the mouse cursor back to the link: -> The hovercard disappears and directly reappears
